No official news of a contract agreement
The www.postalnewsblog.com has reported "a tweet from the Mid Florida APWU Local claims the union and the USPS have reached a contract agreement." [Reference: http://www.postalnewsblog.com/2011/03/12/report-apwu-and-usps-reach-contract-deal/]. However the PostalReporter News Blog [Reference: http://www.postalreporternews.net/tag/apwu-contract-negotiations/] reports the "USPS Denies Contract Agreement Reached With APWU".
In an effort to investigate the report, we went straight to the most applicable source, the APWU. A search of the APWU "Contract Negotiations News" page has not posted an update, at least at the time of this writing, since February 24, 2011. Therefore there is no official news as of yet.
